Air quality officials and enviros on Friday announced a deal that would set an exact course for cleaning up smog in Los Angeles for the next 10 years and end a quarter of a century of costly feuds and litigation. Under the settlement, which still must be approved by a federal judge, the South Coast Air Quality Management District would adopt detailed pollution rules targeting sources as varied as household paints, charbroilers, and cleaning solvents, and the board would have little room to veer from the 10-year goals, whatever the politics or economic fortunes of the next decade. Enviros hope the U.S. EPA requires other smoggy regions, such as Texas and the Northeast, to follow similar plans.
